-vice of this character, which may be readily and quickly applied to a wheel of an automobile, and the wheel raised without much eliort on the part of the user."l With the ordinary hand power lifting jack, considerable labor is required to lift an automobile wheel tree from the ground and unless the brakes are set tight, there is danger of the vehicle moving slightly after the wheel has been raised, and this may cause serious damage in case the tire has been removed and the vehicle moves suilieiently to tilt the jack over. With the present invention, the manual labor of lifting the wheel is dispensed with, and all that is necessary forthe user to `do is to attach the device to the i wheel and move the vehicle aV few .inches which may bedone by driving the vehicleforward or backward through such distance. The invention consists therefore in a new article of manufacture capable of being readily'attached to a wheel and having a base portion spaced below the tire, and capable of raising the wheel when the latter is rotated. It further consists with several cal section taken on line 3-3 of Fig. 2,'

but showing the lifting device in end elevation.

Referring to said drawing, the reference numeral 5, designates an automobile wheel of ordinary and well known construction having` the usual elly 6, 'and spokes 7. Gn the folly is secured a rim 8, to which is secured a pneumatic tire 9.

The lifting deviceis seen at 10, and may be constructed of steel;v iron, brass, aluminum or vother desirable metal, and may be forged or cast as desired. Saidl lifting del Patented Nov. 6, i938?.-

vice has a comparatively, wide base 11,.pref

erably of rectangular formation, from which rises a standard or upright member 12. i

The base 11. is adapted to underlie the tire of a Wheel when in use and the upright member 12, to stand along the side 'of the treadjacent the body of the vehicle. The uppery end poi-tion 13, of the upright member 12, is oset with respect to the lower portion, and is adapted to be placed against the felly of the wheel and. secured thereto. The extreme upper end may have a flange 14, extendinaY laterally away from the oset portion 13, and adapted to bear against spokes of the wheel.'

Strengthening ribs 15, are formed upon one face of the upright member, and said ribs are continued under the base 11, as at 16. Said ribs 15, extend in lines approximately radial with respect to a wheel to which it is applied, and the end portions 17,

of the base 11, curve up slightlylto facilitate the opera tion of the device. A

Secured to and projecting from the odset end portion 13, in the. same direction as the base, are bolts or screw threaded pins 18, which are' provided with nuts 19, lupon theirouter threaded ends. Said screw threaded pins may be secured to the o'set end portion 13, by forming' holes in said end portion, ta pping the holes and screwing the pins into them.

ln the ellies of automobile Wheels, to which thislilter is applied, holes are drilled on the side opposite the tire valve, said holes being drilled from one face of the felly to the other face. The holes are spaced apart to receive the screw threaded pins 18. The uprightmember may be formed with openings to lighten th same, and may be formed with additional ,inforcing ribs 20.

ln use, the threaded pins 18, of the lifting device are thrust through the transverse holes of the telly from the inner side thereof, and the nuts19, screwed up tight on said pins. lf' desired, washers may be interposed between the nuts and felly.` It is to be understood that the wheel shouldoccupy a position where the holes therein are considerably above the ground. In Fig. 1, such a position is seen with the lifting device applied to the telly. Ther-carter the vehicle is moved in thel direction of the aigrew "a, in

' sink nto'the ground, and if :it is used on 'hard pavement, the ribs 16, support .structure Afrom the felly in the usual manner.

The tire may now be removed To fie- `tach thedevce from the Wheel, the vehicle is moved forward or backward until the de- Y vice'is free of the ground, the nuts ere then unscrewed and the device removed by witheo secure by A lifting device for automobiles, comprising en upiight memeei1 foi-med with :i base at' the bottom, emi en 055e?, potiou ai; the upper end, adapted '5o bear against the side of the elly of e Wheel, strengthening ribs on one Side' of elle upright member, and under the base, die ribs on the bottom oi' the base extend transversely thereof, lle en portionsV of said base being inclinel upwerdlil, anal means for etaehebly securing said upright portion to a.
